LUBRICATING DEVICE.

Specification of Letters Patent.

Patented March 12, 1907.

Implication filed June 23.1905. Serial No. 266.579.

To all whom it may concern: Be it known that I, WALTER SCOTT, a citizen of the United States of America, and a resident of Plainfield, county of Union, State of New Jersey, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

The present invention relates generally to lubricating devices, and has more particularly reference to means for lubricating the reversing-roll and spindle of a bed and cylinder printing-machine as well as the surface of the reversing-roll itself. The problem of properly lubricating this reversing-roll is a most important one, as will be understood from the following: A machine of the character described is usually provided with a rotating impression-cylinder, a reciprocating bed having an upper and a lower rack, and a gear adapted to alternately engage with the two racks to impart the proper reciprocation to the bed. Suitable means, as end slots on the bed and a roll or square block moving with the gear, are also provided for reversing the motion of the bed at the end of the stroke in either direction. This reciprocating bed, which is very heavy, makes a number of reciprocatlons per minute. In fact, in highly developed types the speed is considerable. Owing to the impossibility of adjusting the air-cushions which aid in retarding the motion of the bed at each end of the stroke to a nicety, considerable strain is frequently placed upon the spindle, as it practically re ceives all the thrust of the bed on the reversal. It will therefore readily be seen that abundant lubrication is necessary upon the spindle carrying this reversing-roll, as well as upon the surface of the reversing-roll itself or upon the members, as shoes, which constitute the end slots. Adding'to these considerations the fact that these parts are located under the machine, where it is diilicult to reach them by hand for the purpose of lubrication. and where there is little available space owing to the proximity of working parts, it will at once be clear that suitable means for properly lubricating the spindle and roll are very desirable.

The object of the invention is, therefore, the production of suitable means for automatically lubricating this spindle and reversing-roll in a simple and efficient manner, and to this end the invention comprises the features of construction and combinations of parts, as will more fully hereinafter appear.

In the said drawings, Figure 1 is a side elevation of a portion of a printing-machine of the character described, with parts broken away, embodying the invention. Fig. 2 is a vertical sectional view on line 2 2 of Fig. 3, showing the gear which engages with the racks and adjacent parts. Fig. 3 is a detail view looking in the direction of the arrow 3 of Fig. 2. Fig. 4 is a plan view of the source of supply of lubricant. Fig. 5 is a detail view showing a modification.

Similar numerals of reference indicate corresponding parts in the different views.

1. indicates a suitable framework mounting the parts comprising the machine.

2 is the im ression-cylinder, and 3 is the reciprocating l fed, the latter provided with an upper and a lower rack 4 and 5 and provided, further, with suitable end slots, as 6. These slots may be of any suitable construction and may be composed of shoes, rollers, bearers, or other members of a similar nature well known in the art. Adapted to engage alternately with the said racks is a rotatable gear 7, whose axis is fixed, except for a slight upand-down movement in the present instance, to engage and disengage with the racks of the bed in a well-known manner. Moving with said gear is a spindle 8, carrying one or more friction-rolls 9 and 10 or a square block or other members adapted to cooperate with the end. slots or with the members composing the same. This roll or rolls or other member by bearing against the members composing the end slots reverses the motion of the bed in the usual way. As will be seen from an inspection of Fig. 1, this roll or other member on the spindle moving with the gear describes the path with relation to the reciprocating bed, (shown by the plotted curve marked. as.) This will give an idea of how diliicult it is to properly lubricate these parts. In order to properly lubricate this spindle, there is mounted a source of supply 11 on the bed, which preferably takes the form of an oil-cup 12, having a wick 13 projecting out therefrom, with which one or more ducts 14 and 15 in the spindle are adapted to coincide at stated intervals. In the present instance the relation of the parts is such that the gear makes three revolutions to each reciprocation of the bed or to each complete movement in both directions of the said bed. As will be noticed, the source of supply is located at that point 16 of the bed nearest to the path of the friction-roll and spindle while the said roll is out of engagement with the slots. It will thus be seen that these ducts coincide once to every three revolutions with the said source of supply or once to each complete movement of the bed, or, if the parts were differently arranged, say once to every four revolutions. It will of course be understood that a similar source of supply might be located on the upper side of the bed, as indicated by 19, whereby the spindle would. be lubricated automatically twice to every complete movement of the bed or twice to every three revolutions of the 'ear.

g In addition to the foregoing it is desirable to properly lubricate the end slots. or members composing the same or to lubricate the outer surface of the friction roll or rolls or other members carried by the spindle. To this end there is a trough 20 placed 011 the reciprocating bed adjacent to the other source of supply of lubricant, or it may form a part thereof, if desired. In. this trough are located one or more springs, as 21 and 22, adapted to support pieces of wick or other material for conveying the oil or other lubricant out of the trough. It will be understood that when the friction roll or rolls come adjacent to the said trough that it will travel over the wick resting on the surface of the spring and in this manner will have frictional engagement with the said wick under tension, thereby causing a rotation around its own axis, so that the entire surface, or substantially so, is covered with the lubricant. It is apparent that the easiest way to lubricate the outer surface of this roll or rolls is to do so when they are out of engagement with the end slots, and. the easiest way to lubricate the end slots is by applying the lubricant to the surface of the roll or rolls. It is of course also obvious that a duplicate of the trough may be located on the upper side of the bed in a manner similar to the second lubricating device for the spindle.

In Fig. 5 is shown a modification. In this view the parts composing the invention are substantially the same as those described in connection with the structure shown in Figs. 1, 2, 3, and 4. In this instance, however, the two racks 23 and 24 of the bed are located in different planes, and the gear 25 engaging therewith moves sidewise in and out of engagement with the said racks. In this instance the reversing-roll and spindle (indicated by 27) is carried on an arm 28, mounted on the same shaft as the gear 25, or it might be mounted directly on the gear and slide back and forth with the same.
